[This is a re-post of a post from two years ago on, you guessed it, March 14.]
This morning my brother (an engineering nerd, let it be known) emailed to wish me "Happy Pi Day."
Pi, as you know, is the mathematical ratio of a circle's circumference to its diameter.
While pi is a constant, it's also infinite.
My kids get a kick out of listening to The Pi Song.
For convenience pi is usually shortened to 3.14, hence Pi Day -- March 14 -- get it? Get it?
Yeah I know, that's what I get for growing up in a family of nerds...
UPDATE: Reader Rob sent me this photo of a pi pie. He said, "Hmmm, looks like raspberry... There's a nerd joke in that..."
Not sure what the nerd joke might be, so if anyone knows, feel free to elucidate.
